In industrial environments where exposure to chemicals, high pressures, and extreme temperatures is common, choosing the right rubber seals is critical to maintaining equipment performance and safety. As one of Europe’s leading suppliers of rubber seals, Alanto offers durable solutions that ensure longevity and resistance to harsh industrial conditions. Whether your business operates in oil and gas, chemical processing, or manufacturing, selecting the correct rubber seal can prevent leaks, reduce downtime, and protect your systems.
This guide will walk you through the key benefits of chemical-resistant rubber seals and highlight the top materials – EPDM and Viton that excel in industrial settings.
Why Rubber Seals Matter in Industrial Settings
Rubber seals are a vital component in protecting machinery and preventing leaks, especially in sectors like oil and gas and chemical processing, where equipment is frequently exposed to harsh chemicals, oils, and solvents. Seals ensure the proper containment of fluids, gases, or vapours, while also withstanding high pressure and temperature extremes.
Selecting the right rubber seal material is essential to prevent wear and tear, extend equipment lifespan, and minimise costly maintenance or production interruptions.
Top Industries that Rely on Rubber Seals
1. Chemical Processing
In chemical processing facilities, machinery and equipment are regularly exposed to acids, alkalis, and solvents. Rubber seals used in reactors, piping systems, and storage tanks need to provide strong chemical resistance to prevent leaks and corrosion. Seals made from EPDM are widely chosen for their ability to withstand aggressive chemicals while maintaining their integrity over time.
2. Oil & Gas
The oil and gas industry requires seals that can resist exposure to hydrocarbons, fuels, and extreme temperatures. Rubber seals in these environments must withstand both high pressure and exposure to corrosive chemicals, making Viton seals a popular choice due to their superior resistance to hydrocarbons and ability to perform in high-temperature settings.
3. Manufacturing
Manufacturing industries – especially those involved in the production of pharmaceuticals, electronics, and chemicals – require rubber seals to protect equipment from chemical exposure and to ensure operational efficiency. EPDM and Viton seals are frequently used for their resistance to corrosive substances and temperature fluctuations.
Top Materials for Chemical-Resistant Rubber Seals
EPDM Rubber Seals
Ethylene Propylene Diene Monomer (EPDM) is one of the most widely used materials for chemical-resistant rubber seals, known for its excellent resistance to acids, alkalis, and oxygenated solvents.
Key Advantages
- Chemical Resistance: EPDM rubber seals are highly resistant to a broad range of chemicals, including alcohols, detergents, and phosphate esters, making them ideal for industries that handle acidic and alkaline substances.
- Weather and UV Resistance: EPDM performs exceptionally well in outdoor environments, withstanding ozone and UV radiation, as well as extreme weather conditions.
- Temperature Range: EPDM rubber seals maintain their flexibility and sealing performance in temperatures ranging from -50°C to 150°C, making them ideal for both hot and cold applications.
- Applications: EPDM seals are commonly used in chemical processing plants, oil refineries, and manufacturing facilities where exposure to acids and alkalis is prevalent. They are ideal for gaskets, O-rings, and hydraulic systems.
Viton Rubber Seals
Viton (FKM) is another high-performance rubber material that offers superior resistance to hydrocarbons, oils, and solvents. These seals are widely regarded for their chemical resistance and ability to withstand extreme temperatures and pressure.
Key Advantages
- Superior Chemical Resistance: Viton is resistant to fuels, oils, and chemical solvents, making it the go-to material for applications in the oil and gas industry.
- Heat Resistance: Viton rubber seals can withstand environments with temperatures as high as 250°C, making them suitable for high-temperature industrial applications.
- Durability: Viton’s long-lasting durability makes it ideal for applications where seals are exposed to corrosive chemicals and must maintain their performance over extended periods.
Applications: Viton rubber seals are commonly used in oil refineries, petrochemical plants, and industrial machinery where exposure to hydrocarbons, fuels, and solvents is high. Their durability and heat resistance make them the preferred choice for valve seals, O-rings, and gaskets in extreme environments.
Choosing Between EPDM and Viton for Industrial Applications
Both EPDM and Viton offer excellent chemical resistance, but the best choice depends on your specific industrial requirements:
- EPDM is ideal for applications where exposure to acids, alkaline solutions, and weather elements is common. It is also more cost-effective for large-scale applications where moderate chemical exposure is present.
- Viton is best suited for industries handling hydrocarbons, oils, and solvents, or environments requiring high temperature resistance. Its high-performance characteristics make it suitable for heavy-duty applications.
Key Considerations When Selecting Rubber Seals
When selecting rubber seals for industrial use, several factors must be taken into account to ensure the seal meets the demands of your application:
1. Chemical Compatibility
Understanding the chemicals your seals will be exposed to is critical. Both EPDM and Viton excel in resisting different types of chemicals, so choose the material that offers the best chemical compatibility for your environment.
2. Temperature Range
If your application involves extreme heat or cold, make sure to choose a seal material that can perform well under those conditions. EPDM seals are suitable for moderate temperatures, while Viton is more appropriate for high-temperature applications.
3. Pressure Resistance
In industries like oil and gas, where equipment is subject to high pressures, it’s essential to select a seal material that can maintain its integrity without deformation. Viton is particularly known for its resistance to high pressure and harsh environments.
4. Durability and Lifespan
While initial cost is an important consideration, selecting a durable seal material can lead to long-term savings by reducing the frequency of maintenance and replacements. Viton seals typically offer better longevity than EPDM in extreme conditions.
